Metaldyne LLC and Stackpole International, Engineered Products Division agreed to share technology under a technical agreement allowing both companies to expand their product offerings in line with engine fuel-efficiency trends. Specifically, the combined expertise of both companies would support their abilities to offer engine balance-shaft systems with integrated variable-displacement oil pumps. Metaldyne and Stackpole will work together to design balance-shaft assembly systems based on Metaldyne’s balance shaft system technology combined with Stackpole’s variable-displacement oil-pump technology.
